Under dry conditions common to Central Texas, root activity of corn in the upper few cm of soil may be extremely limited thus impeding acquisition of immobile nutrients such as P. Deep placement of fertilizer P to enhance corn yield was evaluated in reduced and conventional tillage systems. During the 2001 growing season, cotton was planted on two adjacent sites, followed by corn in 2002, 2003, and 2004 on one of the sites and in 2002 and 2004 on the other site in an alternate-year rotation with cotton. The soil type at both sites is a Burleson clay. The study design was a randomized complete block with experimental units replicated three times. Conventional, strip, and no till tillage treatments represented main plots, which were split into 8-row sub plots with fertilizer placed at either 5 or 15 cm below the soil surface with a knife-type applicator. Soil samples collected across sites and years from plots under conventional tillage with shallow fertilizer placement showed that P was stratified in the surface 23 cm. Interactive effects of tillage and fertilizer placement on corn yields were not found in the current studies irrespective of crop rotation. For the cotton-corn rotation, tillage had no effect on corn yield during 2002 or 2004. Deeper fertilizer placement increased corn yield in 2002, a noticeably dry season, but not in 2004. In continuous corn, fertilizer placement did not statistically affect yield; however, increased levels of tillage increased corn yields in 2003 and 2004. Deep placement of P fertilizer for corn grown in the Texas Blackland may be beneficial to enhance positional availability in dry seasons.
